Solution

Solution Steps

Step 1: Determine the Electron Group Geometry

According to VSEPR (Valence Shell Electron Pair Repulsion) theory, the electron group geometry is determined by the total number of electron groups around the central atom. In this case, there are 5 electron groups (2 bonds and 3 lone pairs). The electron group geometry for 5 electron groups is trigonal bipyramidal.

Step 2: Determine the Molecular Shape

The molecular shape is determined by the arrangement of the atoms (bonds) around the central atom, considering the lone pairs. With 2 bonds and 3 lone pairs, the molecular shape is linear. This is because the lone pairs occupy the equatorial positions in the trigonal bipyramidal geometry, leaving the two bonded atoms in a linear arrangement.

Step 3: Determine the Bond Angles

In a linear molecular shape derived from a trigonal bipyramidal electron group geometry, the bond angle between the two bonded atoms is $180^\circ$.
